- More compression artifacts
- Faster rendering
- Good for quick checks
```
### Medium Terminal (120x50)
```
- Balanced detail and performance
- Recommended default
- Good for most use cases
- Clear text readability
```
### Large Terminal (160x80)
```
- Maximum detail
- Best for inspection
- Slower rendering
- Shows more screen area
```
## Performance Comparison
### Standard Mode (500ms)
```
Frame time: ~500ms
FPS: ~2
Detail: Medium
CPU: Moderate
Use: General monitoring
```
### High Detail Mode (1000ms)
```
Frame time: ~1000ms
FPS: ~1
Detail: High
CPU: High
Use: Careful inspection
```
### Fast Mode (200ms)
```
Frame time: ~200ms
FPS: ~5
Detail: Lower
CPU: Very High
Use: Real-time monitoring
```
## ASCII Art Quality Examples
### High Contrast Content (Good)
```
Clear text, buttons, icons
Distinct UI elements
Sharp borders
Easy to read
```
### Low Contrast Content (Fair)
```
Gradients become patterns
Photos lose detail
Subtle colors merge
Recognizable but less clear
```
### Moving Content (Challenging)
```

Fast motion hard to track
Static frames clearer
Pause to examine
```
